The energy that would be released if the mass was converted to energy is 9 * 10^-4 J
<h3>What is Einstein equation?</h3>
According to the Einstein equation, mass and energy can be interconverted. This is possible by the use of the equation E = mc^2
Where;
m = mass
c = speed of light
Hence;
E = 1 * 10^-20 Kg * (3 * 10^8 m/s)^2
E = 9 * 10^-4 J

Answer:
866.92 N
Explanation:
mass of shark, m = 92 kg
density, d = 1040 kg/m^3
Volume, V = mass / density
V = 92 / 1040 = 0.08846 kg/m^3
The lift force is the buoyant force acting on the shark is
Lift force = Volume x density of water x g
Lift force = 0.08846 x 1000 x 9.8
Lift force = 866.92 N
Thus, the lift force is 866.92 N.
Hello! You can call me Emac or Eric.
I understand your problem, that question is pretty hard. But I found some information that I think you should read. This can get your problem done quickly.
Please hit that thank you button if that helped, I don’t want thank you’s I just want to know that this helped.
Please reply if this doesn’t help, I will try my best to gather more information or a answer.
Here is some good information that could help you out a lot!
Let’s begin by exploring some techniques astronomers use to study how galaxies are born and change over cosmic time. Suppose you wanted to understand how adult humans got to be the way they are. If you were very dedicated and patient, you could actually observe a sample of babies from birth, following them through childhood, adolescence, and into adulthood, and making basic measurements such as their heights, weights, and the proportional sizes of different parts of their bodies to understand how they change over time.
Unfortunately, we have no such possibility for understanding how galaxies grow and change over time: in a human lifetime—or even over the entire history of human civilization—individual galaxies change hardly at all. We need other tools than just patiently observing single galaxies in order to study and understand those long, slow changes.
We do, however, have one remarkable asset in studying galactic evolution. As we have seen, the universe itself is a kind of time machine that permits us to observe remote galaxies as they were long ago. For the closest galaxies, like the Andromeda galaxy, the time the light takes to reach us is on the order of a few hundred thousand to a few million years. Typically not much changes over times that short—individual stars in the galaxy may be born or die, but the overall structure and appearance of the galaxy will remain the same. But we have observed galaxies so far away that we are seeing them as they were when the light left them more than 10 billion years ago.
That is some information, I do have more if you need some! Thanks!
Have a great rest of your day/night! :)

Answer:
Arrival times of P and S waves
Explanation:
Seismological recording station has a seismometer that senses that motion in the ground, a clock that records time and a data recorded.
The distance between beginning of the first P wave and the first S wave will give you the time the waves are apart.This time value will be used to find the distance between the seismograph and the epicenter of earthquake and you mark it.This is corresponding distance in km to the time in seconds obtained before.You then find the amplitude of the strongest wave and mark it on the right side of chart.Amplitude is the height on paper of the strongest wave.Using a ruler join the amplitude point and the point where you marked the distance to epicenter.This line will cross the magnitude chart at a point which represents the magnitude of the Earthquake.
